Our guest is Dr. Alfonso Davila, an astrobiologist at NASA Ames Research Center! His research focuses on the biological and biosignature potential of terrestrial environments considered to be analogous to extraterrestrial environments, and using that knowledge to develop strategies to search for evidence of life beyond Earth. His current research involves instrument testing in the Atacama desert and Antarctica to inform drilling techniques for the icy regions of Mars.
